Re: Quadra Trac 1 situation/capabilities
They are using the QT2 system in the STR8 with some tweaks. That may be an indication of what case can handle more power, or maybe not.
QT1 is simpler, basically a differential and a chain. The QT2 has many more components (clutches, electric motor, planetary gear set, chain) as well as software. The clutches can wear, the fluid can be contaminated. QD adds a limited slip rear end to the QT2 system.
I don't know the rated torque for either case. QT1 may be simpler but made of smaller components, so I dunno.
If you have enough HP to spin the tires. the QT2 system will put more power to the pavement. So the QT2 would likely be quicker, similar to using a limited slip diff in rear wheel drive cars. The QT2 is heavier, however.
QT1 will be smoother until the point where you start spinning tires, at that point QT2 will be smoother. In everyday routine driving on dry roads, QT1 is smoother. You may hear the transfer case dif whir on turns, however.
